Entwicklung einer schnell schaltenden Bremse und Kupplung für Linearbewegungen zum Überlastschutz in Werkzeugmaschinen

The requirements regarding productivity and quality of highly efficient machine tools are rising continuously. A reliable process safety, along with high machining speeds and accuracy, is an essential property. Thus, collisions between moving and non-moving objects in the workspace are a critical problem [WECK01, P. 111; PILLAND86]. These collisions generally lead to high repair costs up to 23.000 € and long downtimes [KOENEN01; WECK01, P. 375]. Damages of the machine components, such as main spindle and spindle-nut drive-system, are the consequences.
